Latent tuberculosis infection (LTBI) is characterized by immune responses to Mycobacterium tuberculosis antigens without clinical symptoms or evidence of active tuberculosis. Effective LTBI management is crucial for tuberculosis elimination, requiring accurate diagnosis and treatment. In South Korea, LTBI guidelines have been updated periodically, the latest being in 2024. This review discusses the recent changes in the Korean guideline for the diagnosis and treatment of LTBI in adults.

Heart failure (HF) is a major cause of mortality and morbidity in South Korea, imposing substantial physical, emotional, and financial burdens on patients and society. Despite the high burden of symptom and complex care needs of HF patients, palliative care and hospice services remain underutilized in South Korea due to cultural, institutional, and knowledge-related barriers. This position statement from the Korean Society of Heart Failure emphasizes the need for integrating palliative and hospice care into HF management to improve quality of life and support holistic care for patients and their families. By clarifying the role of palliative care in HF and proposing practical referral criteria, this position statement aims to bridge the gap between HF and palliative care services in South Korea, ultimately improving patient-centered outcomes and aligning treatment with the goals and values of HF patients.

Objective: Previous studies have investigated obesity and appetite changes in patients with depression, which consisted of a small age range of adults and used body mass index rather than abdominal obesity. The objective of this study is to examine the relationship between abdominal obesity and the risk of depression by sex and age groups. Methods: This study utilized the National Health Insurance Sharing Service (NHISS) database of South Korea, which includes those over 20 years old and who had undergone a health examination in 2009 and their claims data between 2009 and 2018. The diagnosis of depressive episodes was based on the International Statistical Classification of Disease and Related Health Problems 10th revision. Abdominal obesity was measured by waist circumference (WC) and was divided into six levels (cm). Cox proportional-hazard regression analyses were conducted to examine the relationship between abdominal obesity and the risk of depression by sex and age groups. Results: Among 9,041,751 participants, 1,376,279 were diagnosed with depression. Those with higher WC (90 cm or higher for males, 85 cm or higher for females) showed an increased risk for depression in both sexes (hazard ratio [HR]=1.09, 95% confidence interval [CI]: 1.07–1.11 for males, HR=1.03, 95% CI: 1.02–1.05 for females). Underweight males (WC<80 cm) also showed an increased risk for depression (HR=1.05, 95% CI: 1.04–1.05). Conclusion It has been found that higher WC was associated with increased risks of depression in both sexes. Although underweight males showed an elevated risk of depression, a healthy weight is associated with fewer depression symptoms.

The prevalence of thyroid cancer in pregnant women is unknown; however, given that thyroid cancer commonly develops in women, especially young women of childbearing age, new cases are often diagnosed during pregnancy. This recommendation summarizes the follow-up and treatment when thyroid cancer is diagnosed during pregnancy and when a woman with thyroid cancer becomes pregnant. If diagnosed in the first trimester, surgery should be postponed until after delivery, and the patient should be monitored with ultrasound. If follow-up before 24–26 weeks of gestation shows that thyroid cancer has progressed, surgery should be considered. If it has not progressed at 24–26 weeks of gestation or if papillary thyroid cancer is diagnosed after 20 weeks of pregnancy, surgery should be considered after delivery.

The selected treatment for a nodule that is diagnosed as thyroid cancer is surgery. Imaging and blood tests are performed prior to surgery to determine the extent of the surgery. An Ultrasound (US) of the thyroid and neck should be performed to evaluate the size of the cancer, whether it is multifocal and has invaded surrounding tissues, and the status of the cervical lymph nodes (LNs). In addition to US, contrast-enhanced computed tomography may help detect cervical LN metastasis and evaluate patients suspected with invasive thyroid cancer.Generally, routine preoperative measurement of serum thyroglobulin and thyroglobulin antibody concentrations is not recommended. Integrated 18F-fluorodeoxyglucose positron-emission/computed tomography may be helpful either in patients with suspected lateral cervical LNs or distant metastasis or in patients with aggressive histology.

Differentiated thyroid cancer demonstrates a wide range of clinical presentations, from very indolent cases to those with an aggressive prognosis. Therefore, diagnosing and treating each cancer appropriately based on its risk status is important. The Korean Thyroid Association (KTA) has provided and amended the clinical guidelines for thyroid cancer management since 2007. The main changes in this revised 2024 guideline include 1) individualization of surgical extent according to pathological tests and clinical findings, 2) application of active surveillance in low-risk papillary thyroid microcarcinoma, 3) indications for minimally invasive surgery, 4) adoption of World Health Organization pathological diagnostic criteria and definition of terminology in Korean, 5) update on literature evidence of recurrence risk for initial risk stratification, 6) addition of the role of molecular testing, 7) addition of definition of initial risk stratification and targeting thyroid stimulating hormone (TSH) concentrations according to ongoing risk stratification (ORS), 8) addition of treatment of perioperative hypoparathyroidism, 9) update on systemic chemotherapy, and 10) addition of treatment for pediatric patients with thyroid cancer.
